Abstract

Cardiogenic shock (CS) is uncommon in patients suffering from acute myocardial infarction (AMI). Long-term outcome and adverse predictors for outcomes in AMI patients with CS receiving percutaneous coronary interventions (PCI) are unclear. A total of 482 AMI patients who received PCI were collected, including 53 CS and 429 non-CS. Predictors for AMI patients with CS including recurrent MI, cardiovascular (CV) mortality, all-cause mortality, and repeated-PCI were analyzed. The CS group had a lower central systolic pressure and central diastolic pressure (both ). AMI patients with hypertension history were less prone to develop CS (). Calcium channel blockers and statins were less frequently used by the CS group than the non-CS group (both ) after discharge. Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score, CV mortality, and all-cause mortality were higher in the CS group than the non-CS group (all ). For patients with CS, stroke history was a predictor of recurrent MI (). CS, age, SYNTAX score, and diabetes were predictors of CV mortality (all ). CS, age, SYNTAX score, and stroke history were predictors for all-cause mortality (all ). CS, age, and current smoking were predictors for repeated-PCI (all ).
